How do I Fix a Jumpy Video Played on the Computer?
Every process or application running on your computer takes up precious resources. When you are running multiple programs and trying to watch a video at the same time, things can get a bit choppy. Video playback takes up a lot of computer power as it is, so reducing the strain on the computer will help increase the quality of the playback. Closing processes and applications, as well as adjusting the buffering speed, will help to provide smooth video playback.
Windows Media Player
Open Windows Media Player and select the "Now Playing" tab.
Select "More Options" from the drop down menu beneath the "Now Playing" tab.
Choose the "Performance" tab and click the box next to "Buffer" to highlight the options.
Type a higher number into the box next to the "buffer" category. The default number is 5 seconds, but a higher number will increase the buffer speed. However, the higher the number, the longer it will take the video to begin playing.
Click "Okay" to close the options menu and resume video playback.
Open Quicktime and select the "Edit" menu from the top.
Highlight "Preferences" and choose "QuickTime Preferences."
Check the "Direct Sound" option beneath the "Play Audio Using" category.
Adjust the "Audio Output Device Latency" number if the issue persists. A high number will result in a longer load time but will decrease the chance of buffering due to audio issues.
Press "Ok" to close the window and resume playback.
Close Unnecessary Applications and Downloads
Close any running programs you are not currently using. The programs that you are not using require system resources that may cause the video playback to become choppy.
Stop any downloads that may be running in the background. These downloads will use bandwidth and cause Internet video playback to become choppy.
Open Mozilla FireFox, select the "Tools" option and choose "Downloads." This will display a list of current downloads. If anything is downloading, either pause it or cancel it.
Look for any minimized download windows in the task bar if you use Internet Explorer. Cancel or pause any current downloads and resume video playback.
